COIN CHANGING MACHINE Application filed January 8, 1981.

This invention relates to improvements in coin changing machines. The main object of the invention is to provide an automatic COlIl changing machine which shall be of simple practical construction and design, and adapt machine in which the supply of nickels may be contained in a loose mass m a hopper. Another object is to rovide an improved :5 coin changing or dispensing mechanism adapted to operate with certainty and speed. Gther objects will appear hereinafter.

Accordingly this invention is embodied in a mechanism for the exchanging of coins of as larger denominations into coins of a smaller denomination arranged and constructed as hereinafter set forth and as illustrated in th accompanyin drawings in which Fig. 1 is a ront view of the machine with as the cover removed and details omitted and parts broken away.

contained within a casing 1 which may be of any suitable design and construction, safe and adequate for its purpose. The nickels to be exchanged for coins of larger denominations are contained within a suitably supported hopper 2 which is shown as being in the form of a drum or cylinder having an inlet funnel 3 for admitting large quantities of nickels. No special cover or. locking means for the hopper or in fact for the entire machine has been shown, because they may be of any approved safety type and depend upon thelocation of the machine. The front portion of the hopper 2' isformed with a large annular flange 4, forming a semi-circular coin groove 5 to one side as seen in Figure 11. This coin groove may be on either or on both sides.

Fitting closely within the flange 4 is a coin agitator disk 6 having pins 21 which is mounted on an operatin shaft 7 which is rotated through a train 0 gears 8 or the like from an actuating shaft 9 having an operating handle 10. The shaft 7 and its associated operating elements may be conveniently supported on brackets 11,- 11 in the form-of a yoke attached to a hopper flange 12 which secures the agitator disk 6, Fig. 11.

On the brackets 11 there may be mounted antifriction wheels 13 against which the disk 6 is rotated. To the shaft 7 there is secured a crank 14 having a crank pin 15. One end of a link 16' is pivoted on the pin 15. The other end is pivoted at 17 to a coin pusher pawl 18 in the form of a slide operable in ggides 19 within the coin insert mechanism The mechanism 20 is a coin insert and selecting. device. It comprises a casting or body portion having at its upper end a coin insert opening 22 leadin to a coin insert channel 23 through whic the proper coin falls to operate on a coin delivery actuating dog, and thereafter be pushed into a coin chute 24 from which the coin falls into a suitable receptacle 25, Figure 1'.

The coin insert channel 23 is wide enough I to receive the proper coin but no wider than the diameter of the coin to be exchanged and is provided; with side guides 26 to keep the mo coin in the channel. The latter is further out out as at 27, 28 to provide s ace for throw out levers 29,30 and 31 pivote at 32 to swing into and out of the com insert channel 23. The latter has an opening 33 in theback leading to a throw out coin chute 34, see Fi re 7. Between the two passages 23 and 34 t ere is also a guiding piece or incline 55. The throw' out chute 34 leads to an open cup shaped coin shelf 39 outside the caslng.

The coin chute 24 is offset from the coin channel 23 as seen in Figure 1. The bottom of the insert channel 23 is open as at 36 and communicates with a horizontal coin channel 37 formed between the guides 19 and which leads to the chute 24.

- Directly below the insert channel 23, the horizontal channel has an opening 38 in which the aforesaid coin delivery actuating dog 40 is vertically movable. The dog is at the end of a dog lever 41 pivoted at 42. At its other end the lever is pivoted to a vertical rod 43 which at the bottom is pivoted at 44 to a coin delivery member 45. The latter is ivoted at 46 to a suitable support 47.

e delivery member has a channel 48 and a stop 49 for alignin the channel 48 with a feed chute 50 whic leads from the hopper 2 and which communicates with the aforesaid coin groove 5 therein. 51 is a coin stop at the end of the channel 45.

The arrangement is such that the actuating do 40 is normally held in its upper position within the channel as shown in Figure 1, in which the dog is in a position which prevents inserted coins at the bottom of the channel 23 from being pushed out by the coin pusher pawl 18 without at the same time depressing the do The weight of the dog lever 41 and re 43 is designed to keep the dog 40 in its upper position by gravity and at the same time keeping the delivery memin the channel 48 being prevented ber 45 in non delivering position the coins by the stop 51 frompassing out into the delivery chute 53 and thence into the shelf 39. In the horizontal channel 37 there is also a fixed bottom stop 56 and a cooperating yielding top stop 57 held down by a spring 58.

The operation is as follows: The normal portions of the parts of the machine are as shown in Figure 1. At this time the hopper 2 is filled with nickels which are oured in as it were in a loose mass through't e funnel 3. It is a feature of the invention that the machine operates without the necessity of stacking the nickels or otherwise arranging them in any particular manner.

When a person desires to change a quarter, for instance, the quarter coin is dropped into the insert channel 23 and, bein heavy enough, it falls straight down, brus ing the throw out levers aside and lands in front of the pusher pawl 18 in the position indicated by the dotted circle 65 in Figure 1. The pererable one com lete turn, the result of which is that the pus er pawl 18 hits the coin and pushes it to the right in Figure 1 into the position indicated y the dotted circle 66 to depress the dog 40 and thence into a tempora control position indicated by the dotte circle 67, where the quarter is held between the fixed and yielding stops 56 and 57.

The depression of the dolg 40 causes an upward movement of the ro 43 to ti the delivery member so that the five nickeg held in the delivery channel 48 may fall out and pass into the cup shelf 39 to be received in exchange for the quarter. The movement is very ra id and as soon as the five nickels have been de 'vered, gravity restores the parts 45 and 40 to normal positions. The machine is then ready for another operation.

At each stroke of the machine a quarter, if inserted, will be changed into five nickels and the inserted coin will be operated to actuate the delivery mechanism and will thereafter beheld 'in'a control position as at 67 for the purpose of inspection through a magnifyin window 60, Fig. 12. At each stroke also, t e nickels withinthe hopper 2 automatically range themselves flat against the agitator disk and are carried around by the pins 21 on the latter or any other suitable agitating and carrying device, to fall into the coin groove 5 from whence they pass into the feed chute 50 and finally into the delivery channel 48.

Of course there is nothing to prevent nickels from passing directly from the hopper into the feed chute 50 without first passing through the coin groove 5. However, it has been found that the latter facilitates the lining up of the nickels in an orderly manner as it were. It will be noted that when the machine is at rest, the nickels fill the feed chute 50 and the delivery channel 48. When the delivery member is tipped, Fig. 2, the delivery chute 50 is automatlcally cut oil from the feed channel and-only the'five nickels in the latter are delivered. 'As the quarters are inserted, they are pushed out, one-after another, by the pusher pawl 40 and fallfrom thehorizontal channel 37 into the-chute 24 and then into the receptacle 25 to be removed. At each stroke of the machine the agitator disk agitates the coins in the hopper. I

If a person drops a smaller coin either by mistake or design into the insert channel 23, the coin, being lighter than a quarter, will in its fall strike the throw out levers 29, 30, 31 and be deflected and thrown out into the channel 34, which may be called the irregular coin channel for purposes of identification and then fall into the cup shelf 39 to be recovered. Should the irregular coin be of such a size that it falls behind. the throw out levers 30 and 31, the latter, being longer insures the coin being thrown out. The guiding piece son then turns the handle 10, giving it prefconnected to two 55, Figure 7 is therefore not the full width of the channel 23 but extends only below the throw out levers 29 and 30 and assists in tilt ing the irregular coin to insure its being thrown out by the longer and heavier lever 31.

This machine therefore provides a supply of nickels, an insert mechanism for regular coins having a throw out device for irregular coins. The regular coin in being pushed into the receptacle 25 operates .to actuate the delivery mechanism to deliver the nickels.

Figure 13 shows a double machine which serves to change for instance quarters and dimes into nickels with one operating mechanism. In this instance the parts are numbered as in the preceding figures, but it will be seen that the crank operates a link 71 pusher pawls 18 and 72. The crank pin 73 operates the link by means of a slot 74 in a well known manner. On the left side of the machine the parts are designed to handle dimes in the insert mechanism 20 and the delivery member 76 is shortened to deliver only two nickels in exchange for a dime.

It will further be noted that the machine will not deliver any coins unless there is a coin in position to be acted upon by the pusher pawls.

When the invention has been illustrated in a preferred form, nevertheless it will be understood that the construction is susceptible of changes and modifications without departing from the principle of the invention or the scope of the appended claim.

For convenience of phraseology the term larger and smaller coin will be used in the claim to designate the coin to be exchanged and to be thrown out and without thereby intending any limitations.

I claim:

In a coin changing machine in combination, a relatively flat drum shaped container for containing a supply of coins in indiscriminate order, open and ormed with an annular coin groove, a disk for closing said open side of the container, coinagitating means on said disk extending into the container, meanssupportmg said disk in movable relation to the container, means for rotating said disk whereby to cause said agitating means to agitate the coins and cause them to pass into said coin groove, a coin delivery member for containmg a given number of coins, a coin feedin chute leading from said coin groove an coin container to said delivery member, avity operated means for normally maintaining said delivery member in coin receivin position with respect to said coin feeding 0 ate a. stop normally preventing delivery of the coins from said delivery member, means for placing a larger coin in a given position with respect to said gravity operated means, a
